596 isn't that a tractor head. lol I'd swap the springs as the Crower are a known quantity, the others aren't even after checked.
probably make a good spring for the tractor head. lol
No it's my stroker head... LOL..
I'll probably run them semi out of the box. I'm not going to cannibalize my good heads.
If and when I can afford to and want to take the heads to the next level I'll likely upgrade the springs valvejob and the port job along with my cam...
